* Transferring a Cisco Unified MeetingPlace call from a Cisco-brand phone to a third-party SIP video terminal is likely to result in an audio-only connection. This is due to differences in the way Cisco and third-party terminals negotiate transport of telephony events. The differences cause Cisco Unified Communications Manager to insert a media termination point (MTP) in the call. Unless a hardware MTP resource is available, this insertion will block the video stream.

* If Cisco Unified Communications Manager causes the connection rate to be lower than the maximum for your global video mode setting (384 kbps for standard rate, 2 Mbps for high rate), then the resolution or frames per second sent by Cisco Unified MeetingPlace may be reduced.

All testing was performed with Cisco Unified MeetingPlace connected to Cisco Unified Communications Manager Release 6.1 or Release 7.0 via SIP trunk. For H.323 testing, the terminal was registered to a H.323 Gatekeeper, which was connected to Cisco Unified Communications Manager through an H.323 trunk. For SIP and SCCP, the terminal was registered directly to Cisco Unified Communications Manager.

Endpoints with the following test results are likely to drop calls when transferring to a breakout session, initiating a #31 dial-out call, or exiting the meeting with #9:

Dial in-fail

Dial out-fail

Direct to meeting-OK or "-"

These video endpoints typically do not correctly support the required media transfer mechanism.

Tested dialing out from Cisco Unified MeetingPlace by using a web browser command or by using the TUI command #31.

Direct to Meeting

Tested dialing out from Cisco Unified MeetingPlace using the scheduled "direct to meeting" mode. The process was to configure a video terminal profile for outdial to terminal, tell the video terminal to skip the meeting entry prompts on outdial, and then invite the terminal to the meeting.

4CIF

Tested whether the terminal worked when tested with 4CIF using H.263.

Result

OK

The terminal was able to enter a meeting using video.

No video

The terminal was able to enter a meeting, but without video or (in Release 7.0.1 results only) with one-way video.

Fail

The terminal was not able to enter a meeting. The failure may have been at initial connection or at meeting entry.

"-"

The terminal was not tested in this mode.

Video Format Support

Table: Supported Video Formats lists the supported video formats for various combinations of the global video mode and the codec used by the video terminal.

Notes:

If Cisco Unified Communications Manager causes the connection rate to be lower than the maximum for your global video mode setting (384 kbps for standard rate, 2 Mbps for high rate), then the resolution or frames per second sent by Cisco Unified MeetingPlace may be reduced.

For a Release 7.0.2 and later system:

H.263 and H.261 are offered only by defining a video terminal profile.

Otherwise, only H.264 will be offered.

For a Release 7.0.1 system:

4CIF is not supported.

All three codecs can be negotiated in high rate without a video terminal profile.

H.263 and H.264 can be negotiated in standard rate without a video terminal profile.
